DENTAL CABINET.

Speoication of Letters Patent.

Patented Oct. 25, 1910.

Application med August 25,1909. Serial No. 514,521.

To all whom 'it may concern:

Be it known that I, SAMUEL C. SIMS, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented a new and useful Dental Cabinet, of which the followin is a specification.

y invention has reference to dental cabinets, such as are commonly used by dentists and other artisans for holding tools and implements conveniently to their work.

The chief purpose lof my invention is to provide a cabinet containing a plurality of drawers or trays, such cabinet being vertically adjustable, so that said trays can be severally brought into operative position, and retained therein. The trays are also supported in such a manner as to be ca able of movement outwardly from the ca inet, and away .therefrom to a point convenient for the use of the tools or material contained therein.

An additional feature of my device consists in the provision of a compartment to be supplied with disinfecting material, which compartment will be 'capable of automat-ically communicating with the tray compartments when the trays are in place therein.

Other features and advantages of my' invention will more fully appear 1n the following specification, reference being had to the drawmgs accompanyin 'the same, in which:

Figure 1 is a front e 'evation of my invention. Fig. 2 is a side view thereof, with one of the side plates removed. Fi 3 is a plan viewof one of the tray receptac es, with the tray in place therein. Fig. 4 shows the two lower com artments of the cabinet, in crosssection. ig. 5 is a detail, showing one of the bracket-arms, in perspective.

Corresponding parts are referred to by similar numerals of reference throughout the several figures.

The device has a supporting frame, comprising a baseplate 1; a pair of box-pillars 2, mounted thereon, and surmounted and united by a top 3.

4 represents a cabinet, or case, ca able of vertical movement between the p1 lars 2, and supported at each side by means of a plate 5, secured to the cabinet, and attached to which 1plate is a cord 6, passing upwardly over pul eys 7 in the upper part of the frame, and provided at its ends with weights 8.

Mounted on each plate 5 are two pair of anti-friction rollers 9, which engage the opposite edges of a channel 10 in the inner wall of the pillar 2, and which, in conjunction with the weights 8, which counterbalance the weight of the cabinet, render such cabinet capable of being easily raised and lowered. This may be accomplished by means of a handle 11, attached to the lower front side thereof.

The cabinet 4 is subdivided` into a plurality of compartments 12, each of which is provided with a tray 13, freely supported therein by means of a bracket-arm 14, hingeably attached at one front corner of the cabinet, and an arm 15, hingeably connected with the arm 14, and to the free end of which the tray 13 is hin eably secured, at one of its rear corners. y this means the tray can be entirely removed from the cabinet, and supported at some distance therefrom. See Fig. 3, broken lines. The.

arms 14 and 15 are of such length that they will each occupy a limited space at one side of the tray 13, when such tray isvfully inserted within the cabinet.

In rear of the compartments 12 is a chamber 1 6, separated from Said compartments by a partition-17, but capable of communieating with said compartments independently by means of-doors 18, in the partition 17, and adapted to be forced open by n'gers 19 on the inner ends of the trays 13, when such trays are inserted completely within the compartments 12. Upon the doors 18 being disengaged by the fingers 19 such doors are closed by means of springs 20.

The chamber 16 is provided with a suitable sterilizin material, and it will be obvious that so long as one of the trays 13 is in position in its compartment the fumes of such sterilizing agent will permeate thereto,

and that upon the withdrawal of such tray from its compartment, the means of communication between such com artment and the fumi ation chamber4 will e automatically close preventing the escape of the fumes.

iliary trays or shelves 22, by which means the instruments which have been used 'may be separated from those which have not been.

In use, the device isloc'ated on the opposite side of the operator from the patient, and facingl him. The cabinet 4 is then stationed at a suitable height for the use of the particular tray in which are the instruments which are being used, it being preferred to have the different trays provided with in- Struments for different classes of work. The tray `which is in use is drawn outwardly from the cabinet, and to a point'where the contents thereof can be conveniently reached.

When that part of the operation which calls for the use of the instruments in such tray4 is completed, the tray is returned to its comar'tment, the cabinet L raised or lowered to Erin the tray which will be next employed to t e desired height, and such last-named tra brought to anv operative position. The too s which have just been used can then be removed and cleansed by the operators assistant.

What I claim as'my invention, and desire to secure by Letters Patent of the United States, is,

l. Aldevice of the class named, comprising a supporting frame; a cabinet, vertically adjustable in said frame, and containinga plurality of tray compartments, oneabove another; jointed bracket-arms, pivotally Supportedin said com movement outwar y therefrom; and -a plurality of trays, hingeably supported by said bracket-arms.

2. In a device of the class named, the combination of a supportingframe; a cabinet, vertically adjustable in said frame,- and containi a plurality of tray compartments, one ove another; a plurality of trays,
